(Cl. 229) ABSTRACT OF THE DISCLOSURE This disclosure relates to a carton for containing a plurality of containers, each having upwardly tapering necks, and to a blank for making such a carton, wherein the carton has upwardly converging vertical wall means which conform generally to the tapering configuration of the upper portion of such containers.

This invention relates to containers and more particularly to an improved carton for container means having upwardly tapering outside surface means and to an improved blank for making such carton, or the like.

Many products such as liqueurs, salad dressings, beverages, and the like, are sold in containers such as bottles each having a comparatively long slender neck which tapers or converges gradually upwardly to the top of such bottle. It has been found that sales are considerably increased upon offering such products for sale in inexpensively produced cartons having adequate strength yet having a pleasing and decorative outer configuration corresponding substantially to the configuration of the bottles to be contained therewithin.

Accordingly, it is a feature of this invention to provide an improved inexpensively produced carton having upwardly converging outside -wall means corresponding to the outer configuration of container means to be packaged therewithin.

Another feature of this invention is to provide such a carton which has high structural strength, requires less material to fabricate than a conventional carton which has the general shape of a parallelpiped, and which is comparatively less expensive to produce than such conventional carton.

Another feature of this invention is to provide an improved carton of the character mentioned which can be made using standard machinery.

Another feature of this invention is to provide an improved carton of the character mentioned wherein the upwardly converging outside wall means of such carton enable it to be easily carried under ones arm, for example.

Therefore, it is an object of this invention to provide an improved carton having one or more of the novel features of this invention as set forth above or hereinafter shown or described.

Another object of this invention is to provide an improved carton blank for making such a carton or the like.

Other objects, uses, and advantages of this invention are apparent from a reading of this description which proceeds with reference to the accompanying drawings forming a part thereof and wherein:

FIGURE 12 is a plan view of a blank used to make a carton which is similar to the carton illustrated in FIG- URE 1 of the drawings and which has its bottom wall means modified as illustrated in detail in FIGURES 9-11.

While the various features of this invention are hereinafter illustrated and described as being particularly adaptable for providing an improved carton for container means such as bottles containing beer and each having comparatively long upwardly converging necks terminating in a closure cap therefor, it is to be understood that the various features of this invention can be utilized singly or in any combination thereof to provide an improved carton for other products and uses, as desired.

Therefore, this invention is not to be limited to only the embodiments illustrated in the drawings, because the drawings are merely utilized to illustrate one of the wide variety of uses of this invention.

In the exemplary embodiment of this invention illustrated in FIGURES l8 of the drawings, an improved container means such as a carton 20 is illustrated. Carton 20 is particularly adapted for containing a plurality of two bottles, such as bottles of beer, and each designated by the numeral 21. Each bottle 21 has a cylindrical bottom portion 22 of circular outline and an upwardly converging long slender neck 23 which is substantially frusto-conical in outline. Carton 20 has an outer configuration along its upper end portion which conforms substantially to the upwardly converging configuration of neck 23 thereby giving carton 20 an upwardly converging configuration which is decorative, has high structural strength, requires less material to manufacture, and is comparatively easy to carry.

As seen particularly in FIGURE 1 of the drawings, each carton 20 has a bottom wall 24, a top wall 25, a pair of parallel spaced apart side wall means or side walls designated by the numerals 26 and 27, and a pair of substantially identical spaced apart end wall means or end walls each designated by the numeral 31 for ease of descrip- [1011.

Bottom wall 24 in this example of the invention is of substantially rectangular peripheral outline having side walls 26 and 27 fastened thereto at its opposite side edges and end walls 31 fastened thereto at its opposite end edges. Bottom wall 24 is formed using extension flap means extending from vertical walls 26, 27, and 31 and such extension flap means are folded into a common plane to define bottom wall 24 as will 'be subsequently described.

Side wall 26 has horizontally extending score means or a score line 34 provided therein approximately midway along its vertical height. Score line 34 defines a substantially vertical portion 35 of side wall 26 extending therebelow and serves as a hinge line about which an upper portion 36 of such side wall is moved so that it converges upwardly and inwardly toward side wall 27.

In a similar manner side wall 27 has a score line 40 extending horizontally thereacross at a position corresponding to the position of score line 34. Score line 40 defines a substantially vertical portion 41 of side wall 27 and an upper portion 42 which is adapted to be hinged inwardly about score line 40 so that it converges upwardly and inwardly toward side wall 26.

Portions 35 and 41 of side walls 26 and 27 respectively are substantially rectangular in peripheral outline and in this example have equal areas. Similarly portions 36 and 42 are also of rectangular outline and have equal areas.

Each end wall means or end wall 31 has score means such as a horizontally extending score line 43 extending thereacross so as to adjoin the terminal ends of score lines 34 and 40 in side walls 26 and 27 respectively at each end of carton 20. In a similar manner as described in connection with score lines 34 and 40 in side walls 26 and 27 respectively, score line 43 defines a lower vertically extending portion 45 of end wall 31 which is of substantially rectangular outline. A substantially trapezoidal portion of end wall 31 designated by the numeral 46 extends above score line 43.

Trapezoidal portion 46 of each end wall 31 has inclined side edge means shown as a pair of inclined side edge means or side edges designated by the numerals 47 and 48 and which are of equal length. Thus, the trapezoid defined by portion 46 is an isoceles trapezoid which helps give carton 20 a pleasing appearance. Side edges 47 and 48, in effect, limit the amount of inward movement of the upper portions of side walls 26 and 27 and thus establish their outer configuration.

As seen particularly in FIGURES l and 2, side edges 47 of end walls 31 engage upper portion 36 of side wall 26 to limit its inward movement. Similarly, side edges 48 engage upper portion 42 of side wall 27 to limit its inward movement.

In this example of the invention side edge means 47 and 48 are provided only along the upper end portion of each wall 31, with carton 20 in the closed position shown in FIGURE 1; however, it will be appreciated that side edge means may be provided along the full height of its associated end wall or along any portion thereof so as to control the outer contour of an adjoining side wall means in any desired manner.

As seen particularly in FIGURES 2 and 8 of the drawings, each end wall 31 is formed initially as an integral unit of subtsantially rectangular outline which enables easy insertion of comparatively large lower end portions 22 of bottles 21 within carton 20. Once bottles 21 have been placed in position the upper end portions 36 and 42 of side walls 26 and 27 respectively are folded inwardly about their respective score lines 34 and 40 to define carton 20 having the gradually converging upper end portion.

Each initially substantially rectangular end wall 31 has a pair of symmetrically arranged inverted right triangular portions designated by the numerals 51 and 52 defining its opposite top corner portions. Side edge means 47 and 48 define the hypotenuses of right triangular portions 51 and -2 respectively. Upon closing carton 20 it is seen that right triangular portions 51 and 52 are adapted to lie substantially coplanar with adjoining side walls 26 and 27 respectively.

The integral right triangular portions 51 and 52 hold upper portion 46 of each end wall 31 so that it is inclined toward :an opposite end wall 31. Carton 20 thus has two pairs of substantially vertical walls having upper end portions which converge upwardly and define an upwardly tapered streamlined configuration which conforms generally to the tapered configuration of the slender frusto- 4 conical neck portions 23 of bottles 21 carried within carton 20.

Each end wall 31 of carton 20 is preferably fastened along the full height of its side edges to side walls 26 and 27 as illustrated in the drawings. Of course, it will be appreciated that in some applications of this invention it may be desirable not to fasten, for example, the upper end portion of each end wall 31 which is similar to portion 46 in the manner illustrated and merely push such upper end portion inwardly against an associated bottle carried within the carton while using side edge means thereof to limit inward movement of adjoining side walls.

Extension flap means is provided extending from one of the side walls of carton 20 and in this example of the invention such extension flap means is designated by the numeral 55 and extends from side wall 26. Extension flap 55 defines top wall 25 and closure flap means for carton 20.

Extension flap 55 is foldably connected to the top edge of upper end portion 36 of side wall 26 along a score line designated by the numeral 56. Extension flap 55 also has a second score means or a second score line 57 provided therein and arranged parallel to score line 56. Score line 57 defines the outer edge of top wall 25 and a closure flap 60 extends beyond score line 57 and is adapted to be folded against the outside surface of upper end portion 42 of side wall 27.

Cooperating fastening means is provided in closure flap 60 and in upper portion 42 of side wall 27 to enable repeated easy fastening and unfastening of the closure flap 60 for carton 20. In this example of the invention such fastening means comprises a substantially rectangular flap portion 61 extending from side wall 27 and having a pair of tabs extending from its opposite side edges and each designated by the numeral 62. Closure flap 60 has a pair of cooperating spaced apart substantially U-shaped cuts each designated by the numeral 63 provided therein and each being adapted to receive an associated tab 62.

As will be seen in FIGURES 1-3 of the drawings, closure flap 60 is first moved downwardly into position against the top outer surface means of side wall 27 while holding flap portion 61 outwardly. Each tab 62 is then inserted in an associated U-shaped cut 63 to thereby fasten closure flap 60 firmly in position. The action of tabs 62 together with coopearting U-shaped cuts 63 provide a locking closure at the top of carton 20 which is readily fastened and unfastened.

The dimensional arnangement and action of top wall 25 and closure flap 60 is such that upper portions 36 and 42 of side walls 26 and 27 respectively are held urged toward each other in an upwardly converging manner so as to define the upwardly converging outer configuration of carton 20 shown in FIGURE 1 of the drawings. Furthermore, triangular portions 51 and 52 of each end wall 31 support trapezoidal portion 46 along its opposite sides while defining the amount of converging by an associated end wall.

As seen particularly in FIGURES 5-7 of the drawings carton 20 has a bottom wall which is defined by a plurality of four flaps '65, 66, 67, and 68 extending respectively from side wall 27, one end wall 31, side wall 26, and the opposite end wall 31. Flaps -68 are adapted to be folded into a common plane to define bottom wall 24.

A pair of locking tabs each designated by the numeral 71 is provided in a locking flap portion 70 of extension fiap 67 and such pair of tabs 71 is adapted to be inserted in a pair of cooperating substantially U-shaped angled cuts 72 provided in extension flap 65. Locking tabs 71 may be inserted in position in any suitable manner and are preferably inserted so that flap 67 defines the exterior surface of bottom wall 24 and tabs 71 extend through their associated cuts 72 to the interior of carton 20. Tabs 71 may be inserted in position by hand or may be suitably inserted in position using machiery having a rod assembly,

or the like, which engages each tab and pushes it into locking engagement.

Thus, it is seen that carton 20 is formed having a plurality of exterior vertical walls in which the upper end portions of such walls are adapted to converge upwardly toward each other to define a carton having a pleasing appearance and high structural strength. The converging upper end portion of the vertical exterior walls of carton 20 enables such carton to be readily used to contain 'bottles having slender tapering necks, such as bottles of beer, or the like.

Carton 20 can be made in any suitable manner and made from any suitable foldable material. It is preferably formed from the carton blank 75 illustrated in FIGURE 8 of the drawings. Blank 75 is made of carborard, or the like, having a side such as the exposed surface thereof laminated with metallic foil, such as aluminum-containing metallic foil, or the like, suitably colored, embossed, imprinted, or remaining plan as desired.

Blank 75 is suitably cut and scored and includes a series of parallel rectilinear score or fold lines 76, 77, 78, and 79 defining the lateral extent in one direction of wall 27 extending beyond score line 76, one end wall 31 between score lines 76 and 77, side wall 26 between score lines 77 and 78, the opposite end wall 31 between score lines 78 and 79, and a closure flap 83 extending beyond score line 79. Flap 83 is suitably fastened as by glue, or the like, to side wall 27 to define an open ended tubular structure prior to fastening bottom wall 24 in position.

The main central body of blank 75 is substantially rectangular in peripheral outline and is defined along one edge by a score line 84 extending the full length of such blankperpen-dicular to one terminal end of score lines 76-79. The outer edge of such main central body extends in parallel spaced apart relation from score line 84 and has a rectilinear score line 56 defining a portion thereof. Score line 56 is arranged perpendicular to the opposite terminal ends of score lines 77 and 78 and also extends parallel to score line 84.

In this example of the invention, blank 75 has centrally arranged rectilinear score means defined by aligned score lines 34, 40, and 43 in side walls 26, 27, and both end walls 31 respectively. Also score lines 47 and 48 are arranged from the top edge of their associated end wall 31 so as to intersect the opposite ends of an associated score line 43 and define the hypotenuses of the previously mentioned triangular portions 51 and 52 respectively. Score lines 47 and 48 also contact side edges comprising their associated end walls 31.

As previously mentioned, bottom wall 24 is is defined in blank 75 by a plurality of extension flaps 65, 66, 67, and 68 extending respectively from side wall 27, one end wall 31, side wall 26, and the opposite end wall 31. Flaps 66 and 68, in effect, define supporting end flaps against which fiaps 65 is folded followed in folding sequence by flap 67 upon forming carton 20* from blank 75.

. Flap 67 is fastened in position by suitable fastening means as previously described and comprising locking flap 70 having a pair of locking tabs 71 extending from opposite side edges thereof. Each tab 71 is adapted to be received and held in a substantially U-shaped cut 72 provided in flap 65. U-shaped cuts 72 are provided in flap 65 in spaced apart relation and are arranged therein to provide optimum holding.

Blank 75 is folded to define carton 20 by first folding along score lines 76-79 and fastening closure flap 83 in position against side wall 27 using glue or other suitable means. Extension flaps 65-68 are then suitably folded in position, first folding flaps 66 and 68 in position followed in folding sequence by flap 65 and finally by flap 67. Locking tabs 71 are then inserted in their associated locking U-shaped cuts 72 provided in flap 65.

The initial configuration of the resulting carton is in the general shape of the parallelpiped with an open top. However, the particular configuration and the scores and cuts provided in blank enable carton 20 in its final configuration to have two pairs of upwardly converging walls.

Sidewall 26 in this example of the invention is shown as a rear wall with extension flap 55 extending beyond score line 56 which defines the top edge of wall 26 as previously mentioned. Score line 57 is provided in flap 55 parallel to score line 56 and the distance between score lines 56 and 57 defines the width of top wall 25.

Closure flap 60 extends beyond score line 57 and in this example of the invention is approximately trapezoidal in peripheral outline and has substantially U-shaped cuts 63 provided therein. The base portions of U-shaped cuts 63 are arranged at an angle to each other to provide an improved closing action upon being engaged by associated locking tabs.

Side wall 27 has a pair of symmertically arranged cut means or cuts 92 provided in its upper end portion 42 and such cuts are connected at their lower end by a score line 93. Cuts 92 and score line 93 cooperate to define the previously mentioned locking flap 61 which is substantially rectangular in outline and has a pair of outwardly projecting locking tabs or cars 62. Each locking tab 62 has a short score line designated by the numeral 94 defining its base portion which enables easier fastening and unfastening of such tab.

The width between score lines 56 and 57 corresponds to the width between the top end of score lines 47 and 48 as shown at 95. Thus, it is seen that upon folding side walls 26 and 27 so that they converge toward the top of carton 20 the width shown at 95 is held enabling top wall 25 to provide a well defined top surface for carton 20.

Although it is not absolutely necessary that score lines 34, 40, and 43 be provided in the central portion of blank 75 it will be appreciated that by the provision of such score lines it is an easier matter to fold the upper end portions of side Walls 26 and 27 and end walls 31 in a converging manner toward the top of the assembled carton 20. Also, score lines 47 and 48 enable triangular portions 51 and 52 respectively to be folded substantially coplanar with their associated adjoining side walls 26 and 27 respectively causing the upper portions 46 of end walls 31 to also converge upwardly toward each other.

Blank 75 used to form carton 20 is of simple and inexpensive construction, utilizes a minimum of material, such as paperboard, or the like, and can be cut and scored on standard machinery with minor modification.

Another exemplary embodiment of this invention is illustrated in FIGURES 9l2 of the drawings. The carton and blank of FIGURES 912 is basically similar to carton 20 and associated blank 75; therefore, the overall carton and blank will each also be designated generally by the same numeral as in the previous embodiment followed by the letter designation A. Component parts of carton 20A and its blank 75A which are identical to corresponding parts fo carton 20 and its blank 75 which are illustrated in FIGURES 912 of the drawings will be designated by the same numeral as previously also followed by the letter designation A and not described in detail. Only those component parts of carton 20A and blank 75A that are different from corresponding parts of carton 20 and blank 75 will be designated by a new numeral and also followed by the letter designation A and described in detail. Carton 20A differs from carton 20 only in the construction of its bottom wall means and closure flap means used to initially form an open ended tubular structure upon assembling blank 75A.

Carton 20A has an extension flap A extending beyond that portion of score line 84A defining the lower edge of its side wall 26A. Flap 100A has a substantially rectangular cutout 101A cut from its central outer portion.

Side wall 27A of carton 20A has an extension flap 102A extending from that portion of score line 84A defining its lower edge. Flap 102A is practically identical to extension flap 65 extending from side wall 27 of carton 20 with the exception that extension flap 102A does not have U-shaped cut means, or the like, for receiving locking tabs, or the like.

To assemble bottom wall 24A of carton A, flaps 66A and 68A are preferably first folded in position followed in folding sequence by flap 100A and then by the terminal end portion of flap 102A being inserted within cutout means provided by cutout 101A. Flap 102A thus defines the major portion of the outside surface of bottom wall 24 and does not require separate fastening means.

This sequence of folding the various flaps comprising bottom wall 24A in position is the preferred sequence; however, it will be appreciated that the arrangement of flaps is such that bottom wall 24A may be folded in practically any desired sequence and fastened as by glue, or the like, to still provide a bottom wall of adequate strength.

Another difference which exists in carton 20A is mainly in the manner in which closure flap 83A corresponding to closure flap 83 is provided in blank 75A. Closure flap 83A is formed essentially in two portions designated by the numeral 103A and 104A and extending beyond a score line designated by the numeral 105A and provided to define one edge of side wall 27A. Closure flap portion 103A has an angled edge portion 106A as shown.

The angled edge portion 106A corresponds in angle of inclination to score line 48A. Thus, upon folding blank 75A to form carton 20A, portion 103A is fastened in the plane of one end wall 31A and angled portion 106A enables the upper portion of such one end wall to be folded inwardly toward the opposite end wall 31A.

While two constructions have been shown for forming the bottom wall of the improved carton of this invention in which neither construction requires special fastening means, such as glue, for example, it will be appreciated that such bottom wall may be formed in any suitable manner using practically any configuration and combination of extension flap means. The desired objecfive is to have a bottom wall which can be easily and simply fastened, if desired, and without requiring complicated equipment.

Blanks 75 and 75A may be easily cut and scored using conventional cutting and scoring equipment and without requiring special tooling or special procedures and the particular configurations of such blanks lend themselves to economical production. It will also be appreciated that the particular configuration of each carton 20 and 20A is such that a high strength carton is provided which uses a minimum amount of blank material and provides a decorative appearance.

Terms such as bottom, top, end wall, side wall, bottom wall, top wall, upwardly, downwardly, and the like, have been utilized in this disclosure of the invention merely to define the various positions of the various walls illustrated in the drawings and such terms should not be considered as limiting the scope of this invention in any way.

Thus, it is seen that an improved carton has been provided which is of high strength, uses a minimum amount of structural material, and provides upwardly converging wall means adapted to conform to container means having long upwardly tapering neck means, or the like, to be carried therewithin.

Further, this invention provides an improved carton blank for forming such carton, or the like.
